Object: NGC7635	The Bubble Nebula - Emission Nebula	Const.: Cassiopeia
Camera: SXV-H9	Scope: Tele Vue NP101is	Mount: Losmandy Titan
Filter(s): Hα:R:G:B	Exposure: 10x8m:5x8m:4x8m:4x8m	TeleVue 0.8x Focal Reducer
NGC7635 (the Bubble Nebula) and the open cluster M52 in Cassiopeia. The open cluster Czernik 43 is also visible, just below M52 on the left edge. This image is a stack of 10 eight minute exposures shot through a Hydrogen-alpha filter one day before a full moon in 2004, combined with red, green and blue images taken in 2006. The Hα exposures used for the luminance channel were acquired using an SXV-H9 CCD camera on a Tele Vue NP101 4" f/5.4 refractor. The luminance image is shown in the picture below. The red, green and blue exposures acquired using an SXV-H9 CCD camera on a Tele Vue NP101is. See the RRGB version of this image made using the same data below. The exposures were calibrated, defect-corrected, stacked and color combined using AIP4WIN. This image has been resampled down from its original size of 1392x1040.

 

Hydrogen-α
Object: NGC7635	The Bubble Nebula - Emission Nebula	Const.: Cassiopeia
Camera: SXV-H9	Scope: Tele Vue NP101 @ f/4.3	Mount: Losmandy Titan
Filter(s): Hα	Exposure: 10x8m	Taken during a full moon
NGC7635 (the Bubble Nebula) and the open cluster M52 in Cassiopeia. The open cluster Czernik 43 is also visible, just below M52 on the left edge. This image is a stack of 10 eight minute exposures shot through a Hydrogen-alpha filter one day before a full moon. The exposures were acquired using an SXV-H9 CCD camera on a Tele Vue NP-101 4" f/5.4 refractor using its 0.8x focal reducer. The exposures were calibrated, defect-corrected and stacked using AIP4WIN, and a Wavelet Sharpening filter was applied. This image has been resampled down from its original size of 1392x1040.

 

Object: NGC7635	The Bubble Nebula - Emission Nebula	Const.: Cassiopeia
Camera: SXV-H9	Scope: Tele Vue NP101is	Mount: Losmandy Titan
Filter(s): R:R:G:B	Exposure: 5x8m:5x8m:4x8m:4x8m	TeleVue 0.8x Focal Reducer
NGC7635 (the Bubble Nebula) and the open cluster M52 in Cassiopeia. The open cluster Czernik 43 is also visible, just below M52 on the left edge. This image is a stack of 3 eight minute exposures shot through a red, green and blue filters, with the red filtered image enhanced using a Sigmoid Scaling and used as the luminance channel. The exposures were acquired using an SXV-H9 CCD camera on a Tele Vue NP101is 4" f/5.4 refractor, equipped with its matching 0.8x focal reducer. The exposures were calibrated, defect-corrected, stacked and color combined using AIP4WIN. Note how many more stars are visible in this image than in the one at the top of this page, even though they were created using the same color data. This image has been resampled down from its original size of 1392x1040.
